BLOWUP: Discovered at 16,
Waterhouse became an international “It girl” overnight. “I didn’t
feel like I fit into the fashion world—I’m not a six-foot gazelle.
Burberry was my big fashion break.”

STIFF UPPER LIP: Acting is her
inherent calling. “All anyone does is act—starting as a baby playing
peekaboo for applause. Then, when you get into the business side, 90
percent is dealing with rejection.”

HORSING AROUND: This month she
stars as Cecily of York in the Starz mini-series adaptation of Philippa
Gregory’s The White Princess. “I go against my family, even though the
stakes are high to keep the throne. I ride sidesaddle for the action
scenes.”

90210: Later this year, she’ll trade corset for Corvette as
Quintana in a remake of Billionaire Boys Club. “It’s a true story about
some very naughty boys who get caught up in a Ponzi scheme—the girls
are just as cheeky.”

IN THE CAN: Future projects include The Bad Batch,
with Keanu Reeves, Future World, with James Franco, and Sam (son of
Barry) Levinson’s Assassination Nation.

ENTREPRENEUR: Waterhouse founded
the predominantly pink accessories line Pop & Suki with best friend
Poppy Jamie. “I’m excited about expansion, and I love all the messages
that our color pink encompasses today.”
